    // 触摸TouchView时:
    // 检测顺序: 从 硬件 -> Appdelegate -> UIApplication -> window -> viewController -> self.view -> touchView
    // 响应顺序: TouchView -> self.view -> viewController -> window -> UIApplication -> Appdelegate -> null
    // 如果所有的响应者都无法响应该事件, 则这个事件会被舍弃
    // 两种检测相应者的方法
    //  1> Category 实现 touchBegin的方法
    //  2> nextTesponder
    
    // 例:
    // 1. 响应者不要出边界, 出边界的响应者无法响应
    // 判断当前的点, 在谁的范围内 pointInside:
    BOOL isInside = [touchView pointInside:CGPointMake(10, 190) withEvent:nil];

    // 2. button的点击方法如何实现
    // button点击方法, 通过UIResponder对应的方法实现
    
    // 3. pointInside重写, 实现市区相应能力(return NO)
